This invention relates'to improvements in car construction, and particularly to means for locking the body bolsters to the truck members v ot railway cars.

One object of the invention is to provide means for locking the body bolster to the transom or arch member of the truck ot a railway car, including a king pin and detachable holding device .which interlock with the pin and the arch ortr'ansom member to act as asatety device 'and prevent removal of the pin and separation ofthe body bolster from the truck.

Another object of the invention is to provide a rugged connection between the arch or transom memberof a railway car truck and the truck holsters, wherein the connecting means comprises relatively heavy trunnion members tixed to the truck holsters and co-operating bearing members on the 'arms of the arch or transom members, and wherein the parts are secured together by bolts or pins extending through the trunnion mem-v bers and portions of the arms ofthe transom or arch member.

More specilically, an object of the invention is to provide means vfor locking the body bolster to the arch or transom member of the truck ot' a railway car, which is etlicient and reliable and prevents accidental separation ot the parts, including a king pin extending through the body bolster and into a recess provided in the transom member, the pin being locked to the transom member 'by a sectional locking member' detachably mounted on the transom member and held against movement in a vertical direction with respect to said member and embracing the corresponding end o'l the pin and co-operating withv an annular shoulder thereon, thereby holding the pin against endwise movement in a vertical direction, the opposite end of the pin being headed, and engaging abutment means on the body vbolster to prevent separation of the bolster and the truck member.

lOther and further objects of the invention will vmore clearly appear from the description and claims hereinafter following.

In the drawing, forming a part of this l specification, Figure 1 is a top plan view ot 50 a body bolster and (3o-operating arch vmem- `ber andtruck bolsters ot a railway car, illustrating my improvements in connection. therewith. Figure 2 is Va vertical, longitudinal, sectional view, corresponding substan- 55 tially to the line 2 2 of Figure 1. Figure 3 is a horizontal, sectional view, corresponding substantially to the line 3-3 of Figure 2.

In said drawing, 10-1() indicate the two transversely disposed truck bolster' members 60 y of a railway car truck. `The body bolster of the car is designated by 11, and '12 indicates the arch or transom member of the truck. The transom member 12 is of spider form and has vfour substantially radially projecting' 65 arms 13-13, two of which are disposed in front of the body bolster; and the remaining two in back oit the same. lThe extremities of the arms 13 are supported on the Vbody holsters 10, each bolster 10 being provided with up- 70 standing brackets y14e, eachv of which have spaced trunnion members 15 `formed integral therewith. The extremity of each 'arm '13 provided with a bearing member 16 which has a semi-cylindrical bearing section co-op- 75 erating with the trunnion members 15-l5. The bearing member of each arm 13 is provided with vertical walls 17-'-17, at the opposite ends and centralv partition webs 18` which are' disposed between the two spaced 80 trunnion members of4 each supporting bracket lll. The extremities of the arms 13 are secured to the trunnion portions of the supports 14 by retaining pins 19 which extend through aligned -openings in the trunnion sections 15, g5 the end walls 17 and the partition webs 18 of the corresponding arms. Endwise removal of the pins 19 is prevented by cotter retaining pins inthe usual manner.

It will be evident that the-connections beoo Cil tween the extremities of the arms 13 and the trunnions of the supporting members 14 of the truck bolsters provide an exceptionally.

top bearing surface or seat 21 with which the.

center bearing member of the body bolster co-operates.

ber 2O is provided with a frusto-conical portieri 22 for a purpose hereinafter de-f scribed. The centralportion of the arch or transom member has4 top and bottom wall sections 23 and 24 united the centerby a relatively heavysection 25. As shown, the tcp wall section 23 forms an integral part of the bearing member 20.'k `The central section 25 is provided with a vertically disposed centerpin-receiving opening 26 which is closedv at the bottomv by a wall 27. .The wall 27 is provided with av perforation A28, through which a suitable tool may be inserted to drive out 'the centery pin. The opening 26 is of substantially uniform diameter' throughout Yand is intersected by a traverse opening` 29 which is of vsubstantially rectangular cross section presenting `flat sides,`

The opening 29 1s adapted to accommodate a sec-` wa-lls and flat top and bottoml Walls.

tional'locking device, hereinafter more fully described.

The body bolster ll'of the car 'is provided with a bearing section 120 on the lower side thereof, which is of spherical form and cooperates with'the lbearing section 20 of the transom member. Thecentral portion of the bearing section 120is recessed, as indicated at 122, tocorrespond with the projection 22 on the bearing member of the transom, and receives the same. As will be evident,

= the co-operating bearing members 20 and 120 form the center bearing member proper, and lthe interengaging partsV 22 and 121 prevent lateral displacement of the bearing members with respect to each other. UThe cen- .'jtr'al portion of the body bolster 11 is pro-y vided with a vertical center orvking pin receiving opening 30, whichy is centrally enlarged in diameter, as indicated at 31, and is providedwith an enlarged section 32 at the upper end, adapted to accommodate the The im1v proved connecting means proper for the body bolster and the arch or transom member vofV the truck of a railway car comprises, broadly,

, i a king or center pin A of special design, and

At the center, the bearing memend portion of the pin, which extends into the opening 26 yof the transom member, is cut away circumferentially as indicated at 34C, thereby providing a reduced section and a headed lower end portion, indicated by 35. The head portion 35 is of the same diameter as the main body portion of the pin and may be freely inserted through the opening 30 of the body bolster and the openingv 26 of the transom member.

As clearly shown in Figure 2, the ycut away portion of the pin A registers with the opening 29 ofthe transom member and is of slightly greater extent in height than said opening. The head portion 35 of the pin is of such a height or thickness that it substantially tits the portion of the opening 26 below the transverse opening 29 of the transom member `and has the upper face Ithereof flushwith thebottom wall of said opening 29.`

The sectional connecting member B of my improved device comprises two relatively' heavy blocks vwhich fit the opening 29 of the transom member. Each block is provided with a semi-cylindrical opening` 36 on the inner side thereof, adapted to ft the corresponding side of the reduced cylindrical portion 34 ofthe king pin member A. The two blocks, when assembled and placed in position within the opening 29, substantially embrace the'reduced section of the king pin and prevent verticaldisplacement of the same by engagement with the head section 35 thereof. As will be` evident, movement in a. downward direction of the'pin A is prevented by engagement of thehead with the bottom wall of the 'opening 26. The pin is thus held against vertical ,displacement both upwardly and downwardly by the retaining blocks. To hold the blocks permanently assembled with the arch member and secured to the pin, I provide retaining means comprising two bolts 37 extending through aligned openings in the blocks at opposite sides of the openings 36.

To unite the arch member of the truck of the car and the body bolsterthe pin A is inserted Vfrom the top of the body bolster through the opening 30 and the lower end gaged with the reduced section of the pin A. When thus engaged, the parts of the sectional member B are secured together by the bolts 37. VJhen thus secured togethenaccidental removal of the parts of the sectional locking Vmember B is not possible. The sectional member B snugly fits the opening 29, thereby preventing vertical displacement of the same, and due to engagement of the head 35 of the pin by the bottomy sidesof the blocks of the sectional member upward movement of the pin is positively prevent-ed. It will thus be evident that the head 35 of the pin is effectively locked against upward and downward movement with respect to the transom member by the bottom wall 27 of the opening 26 and the sectional locking member B. The head 32 at the upper end of the pin which co-operates with thev annular shoulder at the bottom of the enlarged section 32 of the recess 30 prevents lifting of the body bolster off of the transom.

From the preceding description, taken in connection with the drawing, it will be evident that I have provided an exceedingly simple and reliable locking means which prevents separation of the body holsters of a car and the trucks of the same; in addition, the means provided is readily detachable, thereby facilitating disassembling of the parts and removal of the truck with respect to the car for the purpose of repairs or replacements.

A decided advantage is obtained by providing means which is readily removable or detachable for locking the king or center pin of the car to the body bolster and transom member of the truck, in that accidental separation of the parts and lifting the body bolster olf of the truck is entirely prevented, thus reducing the danger of accidents due to the separation of the holsters and the trucks.
